摘　　要：通过对压缩过程随机取样进行的统计分析，导出了螺杆制冷机绝热效率的指数分布公式，该式可在工程设计中应用。Based on experimental data under the testing condition of SIO 917-74(TESTING OFREFRIGERATING COMPRESSOR)and GB5773086(TESTING METHOD FOR THEVOLUME TYPE REFRIGERATING COMPRESSOR),a mathematical model is devdopedwith the methods given in statistics. The thermodynamic perfectness in the compressingstage in a screw type refrigerator can be well simulated.The model equation is η_s(t_0,T_k)=e￣(-0.3t_k/(t_0+50)).Errors due to testing data measurernent and other possible factors can be re-duced.A useful method of determining the actual compressing power is proposed,that is,N_t=η_sN_0.
